【摘要】:为构建稳定表达人多药及毒素外排转运体1(h MATE1)的转基因细胞模型,提取人肾总m RNA,经逆转录PCR获得h MATE1 c DNA,借助HindⅢ、KpnⅠ两个酶切位点与pc DNA3.1(+)重组获得重组质粒。将pc DNA3.1(+)-h MATE1重组质粒转染至MDCK、MDCK-h OCT1和MDCK-h OCT2细胞中,经潮霉素B抗性筛选后,以4',6-二脒基-2-苯基吲哚(DAPI)和N-甲基-4-苯基吡啶(MPP+)的积聚实验筛选获得具有良好h MATE1功能的单克隆。测定筛选获得的细胞中转运体m RNA的表达量,并表征其对二甲双胍的积聚或对西咪替丁的转运能力。结果表明,本研究构建的MDCK-h MATE1、MDCK-h OCT1/h MATE1、MDCK-h OCT2/h MATE1细胞模型均高表达h MATE1 m RNA,MDCK-h MATE1细胞对二甲双胍的积聚为转染空载体细胞的17.6倍;MDCK-h OCT1/h MATE1和MDCK-h OCT2/h MATE1细胞对西咪替丁的净外排率分别为17.5和3.65。因此,本研究成功构建了稳定表达h MATE1及共表达h MATE1与h OCT1或h OCT2的细胞模型,可用于h MATE1及其与h OCT1或h OCT2共同参与的药物转运或药物-药物相互作用的体外研究。
